The cries of children with Autism Spectrum Disorder (ASD) contain atypical acoustic features. The cries of typically developing infants elicit automatic adult responses, but little is known about how the atypical cries of children with ASD affect the speed with which adults process them.
We used a reaction time (RT) categorical task to analyze adults' categorization of typically developing cries, atypical (ASD) cries, mammalian animal cries, and environmental noise control sounds. 40 nonparent women ( age = 27 years) were instructed to categorize acoustic stimuli as human infant cries or non-human sounds as quickly as possible.
The RTs for correctly categorizing the cries of children with ASD ( = 831ms, = 27) were slower than RTs for typically developing child cries ( = 680ms, = 6) as well as mammalian animal cries (801ms, = 11) and environmental noise control sounds ( = 692ms, = 10).
This difference may reflect difficulties in adults' perceiving and processing atypical cries of children with ASD, and the findings may have implications for the parent-child relationship and for the quality of care children with ASD receive.
自闭症谱系障碍（ASD）儿童的哭声具有非典型声学特征。发育正常的婴儿的哭声会引发成年人的自动反应，但对于ASD儿童的非典型哭声如何影响成年人处理这些哭声的速度，我们知之甚少。
我们使用反应时间（RT）分类任务来分析成年人对发育正常儿童的哭声、非典型（ASD）哭声、哺乳动物的叫声以及环境噪声控制声音的分类情况。40名非母亲女性（年龄 = 27岁）被要求尽快将声学刺激分类为人类婴儿哭声或非人类声音。
正确分类ASD儿童哭声的反应时间（= 831毫秒，= 27）比发育正常儿童哭声（= 680毫秒，= 6）、哺乳动物叫声（801毫秒，= 11）和环境噪声控制声音（= 692毫秒，= 10）的反应时间要慢。
这种差异可能反映出成年人在感知和处理ASD儿童非典型哭声方面存在困难，这些发现可能对亲子关系以及ASD儿童所接受的护理质量产生影响。
